A construction product sold in Great Britain can carry CE marking or UKCA marking today. The GOV.UK guidance on construction products in Great Britain says CE stays available and that the UK mark, known as UKCA, can be used as well.
That answer only matters once you know the product is in scope. The rules apply when a product is covered by a UK designated standard or a UK technical assessment. A covered product needs a declaration of performance before any mark goes on it. A product outside that scope does not need CE or UKCA under this regime.
A designated standard is a product standard approved by the Secretary of State and published by BSI, the British Standards Institution. A UK technical assessment is the route for a product that no designated standard fully covers.
Great Britain here means England, Scotland and Wales. Northern Ireland has its own arrangement, and the rules below do not cover it, apart from one note in the questions at the end.
So the order of checks is scope, then the declaration of performance, then the mark, then reform risk. Settle all four before anyone on your team writes to a UK buyer. After that, outreach is a normal sales step, and the separate question of whether cold email and LinkedIn data use are legal belongs in its own post.
Treat this as a working summary of the official guidance and legislation linked below, and take legal advice on your specific product.
Why I settle compliance before the first UK message
Do construction buyers answer outreach from a supplier they do not know? Over 2 years of cold email and LinkedIn, my team's campaign for a UK maker of fall-protection equipment for construction sites drew replies from AECOM, bp, Skanska, Doka, Altrad and Saipem. It produced 600+ leads and 200+ booked sales calls across 24 countries.
That is why I settle compliance first: buyers at contractors and engineering groups have to defend every product they specify. The UK Government's response to the Grenfell Tower Inquiry Phase 2 report says misleading marketing of products and manipulation of test data led to the use of products that were not suitable for high-rise buildings.
So specifiers check. A clever subject line does not get past them.
I put the proof in the body of the message: past clients, results and case studies, never parked on a page the buyer might never open. For a construction product, the declaration of performance belongs in that same pile of proof. My team writes every campaign in its cold email service that way.
Which mark and route fit your product?
Find your product in the left column, then read across. The table combines the GOV.UK construction page, the general GOV.UK guide to UKCA and CE marking, Business Companion's construction products guide and the 2019 construction products exit regulations.
| Your product | Declaration of performance? | Marks accepted in GB | Who does the assessment | What to do next |
|---|---|---|---|---|
| Covered by a designated standard, third-party assessment required | Yes | UKCA, CE, or CE with UK(NI) | EU recognized notified body for CE, UK approved body for UKCA | Use the mark your certificate actually supports |
| Covered by a designated standard, AVCP System 4 | Yes | UKCA or CE | The manufacturer self-declares | Draw up the declaration, then apply the mark |
| Not fully covered by a standard, but holds a UK technical assessment | Yes | UKCA | UK technical assessment body issues the assessment, UK approved body tests and certifies | Work from the UK assessment document, not an EU one |
| Already legitimately CE marked for the EU | Yes, the one behind the CE mark | CE | Same bodies as for the EU market | Supply to GB without reassessment or re-marking |
| Not covered by a designated standard or a UK technical assessment | No, under this regime | Neither is required here | None under this regime | Do not apply the UK mark, and check whether another product regime applies |
AVCP stands for "Assessment and Verification of Constancy of Performance": the system for assessing a product and then checking that its declared performance stays constant. The system number tells you how much third-party involvement the standard requires, and System 4 is the one where the manufacturer can self-declare for UKCA. In row 1, "CE with UK(NI)" means the CE mark plus the UKNI indication, used when a UK approved body did the third-party work for the Northern Ireland market.
Check row 5 first, because testing and marking a product that never needed it is wasted money.
Which construction products need a declaration of performance?
Business Companion states it plainly: for Great Britain, a manufacturer must prepare a declaration of performance and put CE and/or UKCA marking on any construction product covered by a designated standard or conforming to a UK technical assessment.
The same guide adds that not every construction product sold in GB needs those marks. If a product does need one and goes on sale without it, placing it on the GB market is illegal.
The legal base is the EU Construction Products Regulation as it now stands in UK law. The retained Regulation (EU) No 305/2011 has a whole chapter covering the declaration and UK marking. Article 4 requires the declaration, Article 6 sets its content, and Annex III gives the instructions for drawing it up.
The 2019 exit regulations add two rules worth knowing:
- The UK marking goes only on construction products that have a declaration of performance, and must never be applied to one without it
- EU harmonized standards were replaced by UK designated standards, and after a coexistence period the designated standard becomes the only basis for a declaration of performance
This article does not list every designated standard, because a product-by-product list goes stale fast. GOV.UK publishes and maintains the current list, and your test lab or approved body can confirm which standard covers your product.
One more party carries duties: the importer. Business Companion says importers must ensure that the marking and the declaration of performance were correctly applied. If a GB distributor imports your goods, expect it to ask for your declaration before it signs anything.
When is CE enough, and when does UKCA make sense?
CE is often enough. The GOV.UK construction page says a product that meets EU requirements, including CE marking, can go on sale in GB with no reassessment and no re-marking. Any third-party work behind a CE mark has to come from an EU recognized notified body, the EU term for an independent test and certification body. The UK equivalent is called an approved body.
UKCA has its own conditions. To use it on a product covered by a designated standard or a UK technical assessment, testing and certification must come from a UK approved body. The exception is AVCP System 4, where the general GOV.UK marking guide confirms the manufacturer can self-declare.
Two details from that general guide trip people up:
- It describes a Fast-Track UKCA route built on EU notified body work, but it also names the Construction Products Regulations 2013 as the main case where designated standards are mandatory. For UKCA on construction products, follow the construction page, which asks for a UK approved body
- Most sectors may place the UKCA mark on a label or accompanying document until 11pm on 31 December 2027, but construction products are listed among the exceptions to that rule
There is also a narrow tolerance for older test work. The product safety regulator says it will not take enforcement action solely because UKCA was used on a product that an EU recognized notified body tested for CE marking, as long as that testing happened before 31 December 2022. Do not plan a launch around it.
The marks also carry legal weight with public bodies. Under the 2019 regulations, a public authority in Great Britain may not impose rules that impede the use of a product bearing the UK marking, or CE marking in certain cases.
A practical rule: let the certificate you already hold decide the mark. A UK approved body certificate is a reason to use UKCA. A legitimate CE route with an EU notified body is a reason to stay on CE and spend your time on buyers instead.
What does indefinite CE recognition mean for EU manufacturers?
The phrase comes from general product policy. In 2023 the Department for Business and Trade announced its intention to extend the use of CE marking for businesses indefinitely, applying to 18 regulations it owns. The US International Trade Administration reported that this kept CE recognition in Great Britain beyond December 2024, for areas such as machinery and personal protective equipment.
The same trade.gov page notes that construction products follow different rules, along with medical devices, rail products and marine equipment.
For construction products, the position comes from a 2 September 2024 ministerial statement, summarized on the GOV.UK construction page, which says the CE mark continues to be available and that its longer-term future depends on wider reforms. So in a construction product brochure, use the GOV.UK wording, that the CE mark "will continue to be available", rather than promising "indefinite" recognition.
The upside today: an EU manufacturer can sell one CE marked product line into the EU and into Great Britain without running two certification tracks.
What it does not change:
- Whether the product is in scope at all
- The declaration of performance behind the mark
- Mandatory designated standards for construction products
One more trap. A product sold to construction sites is not automatically a construction product in the legal sense. The retained regulation covers products placed on the market "for incorporation in a permanent manner in construction works" that affect how those works perform. Site equipment can fall under a different regime, such as machinery or personal protective equipment, which carry their own CE recognition terms. Settle which regime applies before you look at any marking question.
What could the 2026 reform white paper change?
The UK housing ministry, MHCLG, ran a public consultation on its Construction Products Reform White Paper from 25 February to 20 May 2026, 12 weeks in total.
The consultation page calls it an "ambitious programme of reforms", and GOV.UK presents it as the next step after the 2025 Green Paper. It is a package of proposals, not law.
Nothing in it changes what you have to do today.
The likely direction shows more clearly in the government's May 2026 Grenfell Tower Inquiry progress report on the construction industry. The government says the single regulator should not test and certify construction products itself. The reforms will instead tighten oversight of the bodies that do conformity assessment.
The same report recalls the Green Paper's proposals. Conformity assessment bodies would need a license from the national regulator and would follow a statutory code. The UK Accreditation Service would gain a stronger oversight role, and the national regulator would supervise the full conformity assessment process.
Two lines in that report matter to anyone selling products. The government wants product performance claims to be "clear, honest and evidenced". It also wants the test results relied on to place a product on the market to be accessible and free of charge.
If you are a foreign manufacturer, watch two things. The body that tests and certifies your product may face tighter rules. And the claims in your brochures, data sheets and sales messages may soon need to be "clear, honest and evidenced" in the same way as your declaration of performance. Neither is a reason to delay the checks in the next section. My rule: every claim you send a buyer should already survive an audit.
What should a foreign manufacturer check before UK outreach?
Run these four rules in this order, before the first message goes out. A prospect's reply is too late to start.
Rule 1: Prove the product is in scope
Name the designated standard or UK technical assessment that covers the product, or confirm that none does. If none does, you are in the last row of the table and your sales story rests on test data and references.
Rule 2: Have the declaration of performance ready
Match the declaration to the standard or assessment from rule 1. Make sure it exists as a file you can send today. "Someone in quality will find it" does not count.
Rule 3: Choose the mark your certificate supports
CE, UKCA or both, decided by which body did the third-party work. Write the decision down, so your sales team never contradicts your packaging.
Rule 4: Name the technical contact and log reform risk
One person answers specifier and technical manager questions. That same person tracks the reform, especially any change to how your test body is overseen.
My team takes on established manufacturers that already have a product on sale and a track record, not companies starting from zero. Even for them, I ask for one product line and one buyer group, held for 12 months, instead of the whole catalog at once. Picking that line follows the same logic as choosing a market before writing any email.
Once rules 1 to 4 are done, add these before outreach starts:
- Your GB importer or distributor named and briefed
- A signed declaration of performance for GB, saved as a PDF anyone on the sales side can attach
- Proof you are allowed to share, such as project references and test reports
What goes in the first message to a UK specifier?
Write to the person who signs off the product, by their real title. When my team builds a list, I insist on the titles that actually decide in the niche, never a generic "manager". For construction products, that usually means specifiers, technical managers and heads of procurement at contractors and engineering firms. My team finds and writes to these people through its LinkedIn outreach service.
Keep the compliance line short. One sentence says which mark the product carries and that the declaration of performance is ready to send. One line of proof names a comparable project or result. Expect the specifier to check your LinkedIn profile before they reply. A profile with only a job title and a headshot gives them nothing to check, and they move on in seconds.
The ask is small: a short call or a reply with the project they are specifying. Sell the meeting, not your product range, in that first message. The rest is in how to write a cold email that gets replies.
Whoever runs your outreach, open the declaration of performance file first. If nobody on the sales side can find it in a minute, that file is your first task this week.
If you ship construction products to Great Britain and want to talk about the outreach that follows your marking decision, book a call.
Questions manufacturers ask before shipping to Great Britain
What counts as placing a construction product on the GB market?
GOV.UK defines placing on the market as the first making available of a construction product on the GB market. In practice, that is the moment a unit is first supplied into England, Scotland or Wales, whether you supply it or your importer does. So the marking and paperwork have to be correct when that first unit ships.
Can a single CE marked product line serve both Great Britain and Northern Ireland?
For the mark itself, yes. GOV.UK guidance says the CE mark stays usable when construction products are placed on the market anywhere in the UK, not only in Great Britain. Northern Ireland still has its own rules on everything else, so check those requirements separately before shipping there.
Should a product carry both UKCA and CE marks at once?
Only when each mark is backed by its own valid route. The UKCA side needs certification from a UK approved body, and the CE side needs work from a body the EU recognizes, unless self-declaration covers both. A second mark without that backing is a compliance gap. If one route already covers your GB buyers, one mark keeps your packaging and sales copy consistent.
What should a manufacturer do on finding a product already on sale without the required mark?
Stop sending further units of that product into GB right away and tell your importer or distributor in writing. Then confirm whether the product truly needs a mark, prepare or correct its declaration, and apply the right marking before any stock moves again. If units have already reached customers, ask a compliance adviser what to do next.
How often should the GB marking decision be reviewed?
Review it whenever something underneath it changes, not only on a fixed calendar. The usual triggers are a revised designated standard, a switch of test or certification body, a new product variant, and the published outcome of the reform consultation. Add a yearly check of the official construction products guidance as a backstop. Record the date of each review so specifiers can see that your stated position is current.
